Airbag control unit Fiat 500 was broken. Hard to believe but they can really repair it! Recommendation!!
Automatically translated · Original: German
From the first phone call, the order processing, to the shipping, everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red airbag light). Thanks to Airbag 24 in Berlin 👍👏. Gerd

What is an Audi A6 4FH Allroad airbag control unit?
The SRS control unit in the Audi A6 4FH Allroad controls the entire restraint system. It evaluates the signals from the crash sensors. In an accident, it determines within milliseconds which airbags and seatbelt pretensioners to deploy.
The unit is installed in the Audi A6 4FH Allroad (2006 to 2011). It works constantly in the background and continuously checks the system for faults. If it finds one, it reports it via the airbag warning light in the instrument cluster.
If an accident occurs, the control unit stores crash data. After that, it is locked.
Why is the Audi A6 4FH Allroad airbag control unit defective?
Most often the cause is crash data left behind by an accident. This also applies if no airbag has deployed. Other causes include ageing of the electronics, cold solder joints, corrosion and moisture at the connectors, and voltage spikes.
A standard diagnostic tool cannot remove stored crash data. The control unit then remains in a fault state. Other causes develop over time. Components on the circuit board age, solder joints develop fine cracks, and moisture causes corrosion on the contacts of the connector.
Voltage spikes also put a strain on the electronics, for example with a weak battery or after a jump start. The defect usually shows itself like this: the airbag warning light stays on permanently, the fault memory cannot be cleared, or the diagnostic tool cannot make contact with the unit.
Common error codes for Audi A6 4FH Allroad airbag control unit repair
The codes for the Audi A6 4FH Allroad mainly relate to internal faults in the control unit, the supply voltage and the squib circuits of the airbags. They are stored in the fault memory and can be read out with a diagnostic tool.
These codes keep appearing on this vehicle. Each one comes with a short explanation.
- 65535 → General internal fault in the control unit
- 00532 → Supply voltage too low, sporadic
- 00588 → Driver airbag squib circuit, resistance fault
- 00590 → Front passenger airbag squib circuit, second stage
- 01217 → Front side airbag squib circuit, driver side, resistance fault
- 01218 → Front side airbag squib circuit, front passenger side, resistance fault
A single code does not yet prove a defect in the control unit. The cause may just as well lie in a connector, a wire or an airbag module. Only the inspection shows where the fault lies.
What part numbers are available for the Audi A6 4FH Allroad airbag control unit repair?
You will find the part number on the label of the Audi A6 4FH Allroad airbag control unit. It determines the exact version, because depending on equipment and year of manufacture, the same model series has different numbers.
Known numbers for this vehicle follow here. The list is not complete.
- 4F0910655K
- 4F0910655L
- 4F0910655R
- 4F0959655B
Compare the number on your unit with the list. This only ensures that it is the right unit. Whether there is a defect is determined by reading out the fault memory and by the inspection.
The route to repair is short. Have the fault memory read out, disconnect the battery and remove the control unit. Then create a repair order online and send in the unit. For inspecting, repairing and testing, Airbag24 usually needs 3–4 working days. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
